Abstract

A parallel arrangement of thin wires has been fabricated in the Al xGa1-xAs/GaAs heterostructure with holographic lithography. The observed anisotropy of the conductivity parallel versus perpendicular to the wires proves the existence of isolated conduction paths. Transverse magnetoresistance is negative at 4 K and exhibits a shoulder at a magnetic field, where the diameter of the cyclotron orbit amounts to 90 nm, which is supposed to be the effective wire width.
